记录ABAP开发的日常——将SmartForms保存为PDF

前言：有同事在项目上遇到一个需求，需要将打印的SmartForms保存为PDF。在标准的事务码PDF!里面有实现相应的功能，但是文件名和路径不能自定义，不能满足客户的要求，我听了，觉得有趣，于是决定研究下，通过debug发现，标准事务码PDF!是调用了几个函数将表单数据进行了转换，然后输出为PDF的，只是几个函数之间的调用，实现起来相对来说比较简单，于是写了个Demo作为研究记录，在这里展示下。

实现步骤演示：

1.创建SmartForms Demo结构

2.绘制SmartForms表单对象

这里为了节省时间，就没有对表单做样式调整。

3.代码实现
